AI Thread Summary
CFD can effectively predict airflow around vehicles and the trajectories of objects ejected from them, influenced by the vehicle's shape, speed, and the object's characteristics. Practical experiments may pose legal risks, such as littering charges. Constructing a wind tunnel is a suggested alternative for testing airflow dynamics. The discussion also references the finite element method as a relevant computational approach. Utilizing free and open-source CFD software can aid in these simulations and analyses.

Trying to evaluate airflow around a vehicle and behind it to calculate where an object would rest after leaving driver side window.

Welcome to PF.
It will depend on the shape and speed of the vehicle, and the characteristics of the object and the launch trajectory.
If you carry out the practical experiment you may be charged with littering.
Have you considered building a wind tunnel ?

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
